Since one of the earlier projects was not output as a e-r graph when the database was designed, I used PD to reverse engineer the original database when I upgraded the project two times, that is, all the tables of the database are built into the E-R graph structure according to the data source, I use PD 15, the Reverse engineering command is " "Reverse Engineer" in the File menu-the reverse engine. Other versions of PD should be in the "Database" menu. The detailed steps are as follows:

1. Start PD and create a new physical Diagram

2. Menu: Database->congfigure Connections popup congfigure Data Connections dialog box

Click the Add Data Source button to pop up the Create New DataSource dialog box:

We select "System Data Source" and the next step:

Data source driver We select SQL Server and proceed to the next step:

Click "Done" to pop up the new data source created to SQL Server, where we enter a name, description, and server name or IP:

Next: Verify login by selecting SQL Server Authentication with user input login ID and password, and entering the login ID and password

Next: Change the default database for the one you want to reverse work on

Next: Complete

Finally, we will appear in the Congfigure Data Connections dialog box that we have just created.
